LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Jan. 24, 1911.

Application filed June 20, 1910. Serial No.'567,858.

To all whom it 'may concern:

Be it known that I, GUY E. STANSELL, a citizen of the United States,residing at Seattle, in the county of King and State of lVashington,have invented certain new and useful Improvements in Loose-LeafBinders.` of which the following is a specification.

This invention relates to improvements in loose-leaf binders; and itsobject is to perfect devices of this class whereby leaves may be readilyinserted or removed as desired.

The invention consists in the novel construction and combination ofparts, as will be hereinafter described and claimed.

In the accompanying drawings which show an embodiment of my invention-Figure l is a plan view with casing of one of the cover-parts brokenaway. Fig. 2 is a longitudinal section taken through 2-2 of Fig. l butwith the clamping collars therein engaged with the posts. Fig. 3 is across section at 3 3 of Fig. l. Figs. ll and respectively, areperspective views of the clamping-frame and one of the clamping-collarsshown in the other figures.

The reference letters A and B designate the top and bottom cover-boardsof the binding and, in the construction illustrated, are connected bysheets A and B of flexible material with tubular members C and D.

Posts E extend through spaced holes F in opposite walls of the member Cand are rigidly secured to the other member in any appropriate way, asby screwing reduced ends c of the posts into blocks Gr provided withinsuch member. These posts furnish supports for the leaves which are to bebound by engaging the same within apertures punched adjacent to the backedges of the leaves.

Loosely fitted within the member C is a rectangularly shaped framecomprised of side bars H and end bars I and K. The bar K is providedwith a screw-threaded hole 7c for engagement with a longitudinallyarranged screw L having a polygonal outer end Z which is engageablewithin the socket of a suitable operating key. M and N are collars, onefor each post, and located within said frame. Between the collars' is aspring O tending to push the collars asunder and, in relatively largebindings, the operation of the spring is improved by employing blocks Pbetween the collars and the adjacent ends of the spring.

It and R are pins extending across the space within the member C andlocate-d to be engaged by the fame-bar I and the collar N to limit theopposite movements imparted thereto through the instrumentality of saidspring when the screw is retracted.

lVith the parts of the device occupying the positions shown in Fig. l,the member C with the connected cover-board A may be detached from thecomplementary parts of the binder, by lifting the former from Y theposts. By replacing the member C and associated parts upon the posts andoperating the screw L against the collar N, the latter is shoved againstthe adjacent post with a consequent retractile movement of the :frame tocause the collar M to be likewise brought into contact with the otherpost and clamp the two posts with the member C through the agency of therespective collars.

The invention claimed, is-

In a binder, a cover, a tubular member incased therein, blocks inclosedin said tubular member, posts having reduced eX- ternally screw-threadedends and internally screwthreaded sockets in their opposite ends andrigidly screwed into said blocks through perforations in one side ofsaid member, another cover, a tube therein, said latter cover and tubeprovided with apertures therethrough to receive said posts which projecttherethrough and from one face of the latter cover, a rectangular collarfor each post, a U-shaped frame within said tube inclosing said collars,a cross-bar positioned in said frame and spaced from one end thereof,further blocks positioned adjacent said collars and having cut-awaysockets in their adjacent ends, a spring interposed between thelatter-named blocks and seated in said sockets and adapted to push saidblocks and collars apart, a pair of spaced stops secured to the insideof the posts by said collars.
